Sonic Nature Fret Polishing File Pack (5-Pack)

Give your frets the treatment they deserve with the Sonic Nature Fret Polishing File Pack. These disposable files make it easy to achieve smooth, polished frets in three simple steps: green to smooth, red to clean, and yellow to buff to a mirror shine. 

Clean, polished frets don’t just look better—they feel better too. You'll notice smoother string bends, easier vibrato, and a more responsive playing experience overall. Each file is good for 2–3 full fretboard polishes, and with 5 in a pack, you're ready for multiple guitars or setups. Not intended for fret levelling.
